Онлайн-статусы, исправление навигации и UI чатов

- Реализован PacketOnlineSubscribe (0x04) для подписки на статус собеседника
- Онлайн-статус загружается из результатов поиска (PacketSearch) при каждом хэндшейке
- Toolbar capsule показывает online/offline/typing вместо @username
- Зелёная точка онлайн-индикатора на аватаре в списке чатов (bottom-left, как в Android)
- Убрана точка с аватара в toolbar (статус отображается текстом)
- Исправлен баг двойного тапа при входе в чат (программная навигация вместо NavigationLink)
- DialogRepository.updateUserInfo теперь принимает и сохраняет online-статус
- Очистка requestedUserInfoKeys при реконнекте для обновления статусов
- Добавлено логирование результатов поиска и отправки пакетов
